This week project would have been very useful when i was little and played with cars but is intended for small models and modeling.

The traffic light system is based on the real who are on Portuguese roads.

In addition to the traffic lights for the car also includes the traffic lights for pedestrians without forgetting the buttons for pedestrians.

The 16F690 microcontroller was used and almost all pins have been used. There is a third button to enter into the maintenance mode making the traffic lights flash the yellow lights until one of the pedestrians buttons is pressed.

After getting all traffic lights completed, i made a small road cross with black cardboard and placed the lights. In the picture below we can see the completed system, although still mounted on an experimental board.
